Vertical Cities at my favourite museum in New York

Taking over the MTA transport museum as my new favourite museum in New York City is the Skyscraper Museum, which encompasses not just fascinating exhibitions and photos, but also incredible architecture. The building itself is designed to make you feel like you are standing on top of an infinitely tall steel and glass structure, and although it only covers one floor of a tiny building in downtown Manhattan, you can imagine being in one of the incredible buildings that the museums tell you about.
The current exhibition was a presentation on New York and Hong Kong as 'Vertical Cities', showing the differences in vertical development and the resulting infrastructures to sustain this 'vertical living'. What was most eye-opening was the picture of New York drawn in 1912 known as 'Future New York, The City of Skyscrapers', which resembles modern day Hong Kong rather than modern day New York, check out the picture to see what I mean. Hong Kong today boasts one of the (if not the?) most vertical skyline in the world, as well as (get this!) a 0.5 mile long escalator, the longest covered escalator system in the world, which gives you a 20 minute ride up through the city for commuters and naturally tourists too; three miles of raised covered pedestrian-only walkways linking key buildings together (oh if only Oxford Street, London and Canal Street, New York had this in place!) and the most slender skyscraper in the world with a width-height ratio of 1:20! Think of the tests needed to be performed on that building before construction even began!
The museum also contained a wooden model of Manhattan, made by Michael Chesko, a man with a lot of wooden pieces, time on his hands and highly skilled craftsmanship. Also a lot of imagination, given that it was not until the model was finished that he actually VISITED New York for the first time from his hometown of Arizona. He used aerial images and stuff to get an idea of the city skyline, from what I remember.
